Abstract
Paraclinoid internal carotid artery (ICA) aneurysms arise between the roof of the cavernous sinus and the posterior communicating artery. Their rupture rate is estimated at 11.4-25%. Ruptured paraclinoid aneurysms typically present with subarachnoid haemorrhage; a new visual deficit as a presenting complaint is distinctly uncommon
